PROBLEM TO BE SOLVED: To provide a method for producing a functional macromolecular solid-state electrolytic capacitor by impregnating a wound aluminum electrolytic capacitor element with the conductive macromolecular solution of high electrical conductivity. SOLUTION: An aluminum electrolytic capacitor element 10, wound by the polyaniline solution of high electrical conductivity is deposited, impregnated with polyaniline and dried later by a dryer maintained at a fixed temperature, so that solvent can be completely removed. At such a time, for impregnation satisfactory impregnation characteristics are presented not only under ordinary temperature and ordinary pressure but also under high temperature and reduced pressure. The dried element is inserted into an aluminum can, sealed and dried by an epoxy resin later, so that the functional macromolecular solid-state electrolytic capacitor 10 can be provided. Such a functional macromolecular solid-state electrolytic capacitor 10 produces such as this has high capacity, low impedance and low equivalent serial resistance(ESR) values, the unit production cost is low, the production process is simple, and highly reliable production characteristics are presented. |
